Alvium USB Cameras User Guide V3.6.4
Camera interfaces
I/O cables and electromagnetic interference (EMI)
Consider for I/O cables by Allied Vision:
• 12319 JST I/O cables without screw lock have no shielding and are designed to
be used with bare board or open housing Alvium cameras.
• For applications without an additional EMC housing, use shielded cables, such
as 12322 JST I/O cables
with screw lock
.
NOTICE
Damage by reverse polarity
If Alvium USB cameras are externally powered with reverse polarity, the cameras
can be damaged.
Power Alvium USB cameras according to the specifications described in this
section.
